s claims. (c1. zoe-51) nie package pf the present invention ispreferably made up of a quantity of sheets, for instanceA folded napkins, which are bundled together into the form of a rectangular stack and s enclosed within a vcomposit wrapper, one section v l5 accompanying drawing, wherein, e

Figure l is a perspective view showing the package of the present invention;

Fig. 2 is a sectional elevation taken on 1ine 22 -of Fig. l: f 20 Fig. 3 is a sectional plan view taken on line 3 3 of Fig. 1;

Fig. 4 is a'view of the blank from which the sleeve section of the wrapper is formed; and

Fig. 5 is a perspective detail showing the meth- 8B od of gluing the terminal edges of the cellophane" wrapper section to the sleeve. The compomte wrapper of the present invention includes a. sleeve section I comprising a plane or imperforate back wall II, a top wall I2, $0 a bottom wall I3, and a front Il.. The iront is cut out in its center portion to provideA a window opening I which as shown is of generally rectangular configuration save at one of its corners where the material forming the front is 85 extended inwardly to afford a comer panel I6 for the reception of suitable advertising matter, stock numbers or the like, for identifying the Pakae- The sleeve section ispreferably formed of a 40, continuous strip or blank of relatively still paperboard bent along folding lines I1 and provided at one of its ends with a tab I8 which constitutes an vextension of the back section II and isadapted to underlap the top section I2 and to 45 be glued thereto to furnish an. unbroken band or sleevelik'e enclosure for a stack of\napkins I9, f or sheets similarly arranged and compressed to-V gether. The sleeve section of the wrapper cooperates with a band or strip 2li of cellophane i 50 or similar transparent or semi-transparent mat--v terial, the ends 2l of which overlap the edges of the back section II and are glued or otherwise secured thereto, and the wrapper section is carried across the open ends of the sleeve and I I across the fronjtwindowportion to complete the UNITED STATES -PATEfN'ToFi-*Vlca enclosure-of the stack `within the sleeve. In otherwords, the outer section of the wrapperencircles the stack in a direction at right angles to the inner or. sleeve section, so that the two sections in conjunction afford a com/plete enclosure for the 5 stack within the composite wrapper, tlius serving to protect the stack at all pointsagainst the intrusion of dirt, dust or foreign material, and at the same time the provision of the outer transparent or semi-transparent section permits a dis- 1n play of the contents of the package and affords an attractive appearance and finish for the package as a whole.

, Furthermore, the wrapper of the present invention is one'which permits a stack of napkins l5,

as they are delivered from the folding machine to be quickly and uniformly compressed and enclosed within the sleeve section of the wrapper,

. which results in packages which being uniformly compressed areof uniform dimensions and of 20 substantially rectangular form, so that they may be easily stacked, stored, or fitted into shipping cases of standard size. f

The application of the outer wrapper section to 'a stack thus bundled and enclosed serves to 25 complete the enclosure and protect the exposed edgesjof the sleeve against tearing or abrasion, and particularly serves -to protect the edges of' the window opening and hold them in closely compressed relation against the enclosed stack of napkins or the like, thus permitting the window opening to be made of much larger dimensions than could safely be' employedin the absence of a surrounding transparent section of the character in question. l 35 Furthermore, the employment of the surrounding wrapper section serves to reinforce the sleeve itself against bulging or disruption and permits A the napkins or the like to be maintained in the form of a, well compressed package and in form 40 to aord an 'attractive display when placed upon a retailers counter, since the employment of cellophane or the like affords the visibility required to display the embossing or other decoration applied to the napkins.

The package, moreover, affords a practical receptacle for any unused portion of the contents inl the home, since the cutting away of the outer wrapper 'section permits the napkins to be removed singly or in the limited quantitiesljrel quired for immediate use, and preserves the re,-

-mainder of the napkins in stacked condition until required.

The sleeve formed from a strip of relatively stiff` paperboard bent to substantially rectangular 5l;

shape along folding lines affords suilcient stii- -ness in the walls of the sleeve to maintain the package in substantially its rectangular form, so e,

that the sleeve is not to be regarded merely as a wrapper which configures itself to the formation of the commodity enclosed within it, but is to be regarded as an element which serves to give and maintain the proper conguration to the enclosed stack of sheets.

' (Y Althoughv for many purposes it'is desirable to provide a window in one of the walls of the sleeve, it is not the intention to limit the shape of the window to any particular conguration or to limit the location of the window to the front wall of the sleeve, and in some cases -it may ,be desired to omit the window altogether, and to utilize the sleeve either with or without an outer wrapper section, or, if desired, to utilize.y an outer wrapper section formed from non-transparent or semiftrans'parent material. l

'Ihe particular arrangement, therefore, will dpend to some'extent upon the nature of the commodity enclosed andthe extent to which, if at all, it is necessary or'desirable to make ,provision for its inspection while enclosed within the wrap-'I material bent on folding tlines tol aordsubstan- `tially rectangularly disposed walls bearing against the contiguous sides of the stack and coextensive therewith, the ends of the strip being overlapped and adhered together to alord a continuous wrapper surrounding four sides of the stack one of the walls of the sleeve provided with a cut out window opening for exposing the sheets and permitting removal therethrough, and a Wrapping member consisting of a' continuous strip of material surrounding the rst mentioned wrapperI at right angles to the direction of wrapping of the irst mentioned wrapper and serving to overlie and substantially enclose the portions of the stack exposed by the rst wrapper.

2. A rectangular package consisting of a stack of sheets compressedvto rectangular form, and a composite wrapper consisting of a sleeve section tightly embracing the stack of sheets for holding them in compressed condition', said sleeve 10 u section being formed of avsingle strip of relatively .opaque material folded to afford a back wall, a frontwall and connecting walls leaving the sleeve open at its ends, the front wall being provided with a cut out window opening, and 15 a wrapper section in the form of a. strip of relatively transparent material having its ends secured to the back wall and extending across and substantially covering the open ends of the sleeve and across the window opening and furnishing a 20 closure for said open ends and said window and serving to expose the commodity for inspection.

3. A rectangular package consisting of a stack of sheets'compressed into rectangular form, and a composite wrapper consisting of a sleeve sec- 25 'e tion tightly embracing the stack of sheets for holding them in compressed condition, said sleeve section being formed from a single strip of opaque paperboard bent to provide an imperforate rectangular back wall, a front section cut away 30,.

throughout its major portion to aiord a window opening defined by relatively narrow marginal portions, and top and bottom sections connecting the front and rear portions of the sleeve leav- :ing *he ends of the sleeve open, and an'outer 35 wrapper strip of transparent pliable material having its ends adhered to the rear wall Aof the sleeve.y and extending across the front window opening and serving to complete the enclosure of the stacked sheets and permit inspection theren of through the window opening.
